The .cylinder is provided vwith a valve comprisingapair of segmental valve meinbers 11. pivotetl at 12 and simultaneously operated by the right and-left hand screws 13 and 14 enacting with nuts 15 and 'connected 'by the rod 1 6. This rod has collars 17 engaging the upwardly projecting pins simultaneously adjusted as seated maintaining a central inlet tothe ejector chamber;

The ejector comprises a disk-like body memberli) of such diameter that t'sedges are in close proximity to the walls of the cylinder. This body member lies in -aplane below the discharge opening 9 and has an.

upwardly projecting. hub 20"as shown in Fig. VI. A

Blades 21' are secured' upon the face of this disk-like body memberin a 'rearwardly inclined relation, preferably tangentiallyof I have found in practice that withthe blades thus disposed the material' is' rapidly ejected through the discharge opening and the tendj ency for the material'to. pack and thereb noA clog the machine is minimized.

The bottom ofthecylnder has a central cylindrical recess 22'.While.the' ejector has ananniilar flange 23 traveling in this "recess which is effective 'in presenting the material f roin reaching the hearing.

-Further, to' prevent clogging and to4 prevent. th'e material Afrom reaching the hearing, I provide the bottom with a discharge vent 24 positioned at thev side of-this flange 23 and the ejector with the clearing blades 25 disposed radially on the underside of the ejector. .These clearing blades to a. rger-extent prevent the material passing vlow theejector. With the parte thus ar- Mnged I am able to discharge large quantities .of heavy powdery material such-as cementv and lime with very little likelihood of clogging` which is a feature of very great advantage. f

The discharge 9 is provided with a disk 'valve 26 pivoted at 27 and having an open- .4 ing 28 therein' adapted to'be broughtinto land out of register-with the discharge open-' `ing 9. This valve is automatically operted by 'means which Will. be' hereinafter described p scesi@ The machine is controlled by .aweighing weight -lieiiig carried by' the scale mounted on 'the scale beam..

spouts are-'in raised As the carrier is oscillated the spouts are .alternatelybrought into regigister` with the' discharge opening 9. A

The bags 60 areof the seflf-closngtype and arefespeciallydesigned to receive -the spouts. .Tlie bags 'are retained uponthe lao spours by means of the bag holders Gl pivoted at G2 and held yieldingly in engaging position 'hy means of the spring -$5. see Finis. Y and X. rThe operator pushes the halq under the ha;r holders whit-li have serrated faces and are of such length that the pull thereon tends to make the jaw grip the hug more firmly. \\'lien. however, the hiteh 58 is releasei, the spout drops flown- IU wardlv thereby releasing the. bag: and thisv timed with the releasing of the )hitform so that the filled bag is ejeeted. 'l he operator laces :i hay: on the spout whit-h is in non lling: position while the other spout is l5' in filling position so that as soon as the bug! is discharged ,the .spouts are nutotnntieullv shifted.

The. spout eiprier is automntieully shifted. or oseilluted by means of-the enrrier urtuntA i" ing lever (i4 whirh is pivoted on the freine 'at 65 and provided with a roller 66 engaging: the yoke o7 formed in the upper end of the spout earrier, this voke providing :i pam' of seats 68 on the o )posite sides of the' 'i7' pivot of the yoke. he lever is netmited by the springy (il). one end of whieh is ronueeted to the hub 7() of the eurrier. see Figi.` Vl. und the other end is eonneeted to u pin Tl projeeting from the uppe! end of the 3" lever. When the seule. boum is in its initio! position this; actuating spring is plneefl under streets as will boch-ar `from Figs.. l.' and IV of the drawing. so that when the bag earl-ier is lowered by the lowering of 35 the seule beam under load the lever is swung to the opinas-ite end of the yoke. thereby iii-touting the spout carrier. this taking.' phiee :o: mon as the filled bag is disehurged.

,This downwu'llgd movement of the eurrier 4 also brings the "latch 58 into engagement with the trip 72 on the end of the support` ing:l bracket T3 which is mountej on the. frame to projeet through :in opening T4 in the carrier, 'see-I Figs. VI und IX. This l'irueket 73 also serves as u means for sinh ably supporting the carrier, the braeket buv- `-ing r un adjustable serewwith whit-li the. lmssthslidably engages.

To m'relerute'or muse :i tptiek :it-tion of the parts. thereby elosing the vulve uuirkly nml also musing quiek movement. of the connecte l (ports, l provide n n eleetromagnet Ril. the orma'ure of which, not'illustruted, is rminerted ny the rod Si to un arm Si on il roeltshztft T9. This eleetronmgrnet is in torn rontrolled from a :mitch 'lesignuted n.hnrnjby (he Dumont! R() ionliertt-:l lit' the wiresi' to the armature.. The switch illustrated is of the mercury type, it, however, beingI shown conventionally.

The .switeh actuating rod B8 is pivotully eonnerted to the lever 8.() pivoted nth() on the projeetin; r bracket 91. The `wille rod Il?, is provided with a tnppet 3Q adopted to engage this lever on the down stroke of tho rod or when the Seule beam is neluuted by the weight thereon. thereby closing the switeh sind netimting the eleetroinzxgnet, :is stated, to .ueeelerate thc movement ofthe ports` A r-oiled spring: 93 vieldingly supports the trip llever 89 and allows the tappet to return to its initial position, see Fig. XH'.

To loek the eurrier in its aetuated po. i tion l provide n locking dog;r 94 whit-h is pivoted :it 9.7 and is held yieldin'gly in engaging position by the spring SP6. the eugagging: end 9i of the dog being: arranged through :i hole 98 in the frame pit-ee 92' to engage one of the recess-like keepersl l0() in the earrier. :see Figs. IX und XI. As: the carrier moves dms'nwzirdlv this loeking dog' is disengaged. the upper end ofthe keeper hein.;r inelined so that. the dogr is pushed rearwardly. thereby releasingr the carrier for its oseillating movement.

These variousl operations are timed so tlod. :dl the operator is require to do is to plm-e, the bags; on the s muts. As soon :is the rt quired weight o material `has been dis eharged into the bag, the weight of the bug actuales the seule. thereby dis-engaging the spout supporting latch., und, also. when u predetern'uned point is rear-hed the platform is released so that the. bag is ejected. 'hen the parts reach their lower position he urtnating springr under the power storei therein uetuzites the lever 6l und shifts the eu'rrier.
